[0019] like Figure 1-Figure 4 As shown, a PVC pipe raw material mixing device includes a cylinder 1, a cover 2 is provided on the top of the cylinder 1, and also includes: a stirring part, two groups of baffles, a first driving part, a second driving part and an intermediate connecting part, wherein: The cover body 2 is provided with a feeding port, and the bottom of the cylinder body 1 is provided with a discharging port; The stirring part comprises a first half auger 3 and a second half auger 4, wherein the first half auger 3 and the second half auger 4 are spliced to form a complete auger; The two sets of intermediate connecting parts are used to drive the first half auger 3 and the second half auger 4 to be spliced or separated respectively; The first driving part is connected to the first half auger 3 and the second half auger 4 when they are spliced, and is used to drive the first half auger 3 and the second half auger 4 when they are spliced; The two second driving parts are respectively connected to the first half auger 3 and the second half auger 4 when separated, and are used to drive the first half auger 3 and the second half auger 4 to rotate when separated; The baffle portion includes a semicircular baffle plate 5, a bracket 6 is provided on the top of the semicircular baffle plate 5, and the bracket 6 is transmission-connected to a third driving portion; When the first half auger 3 and the second half auger 4 are in a spliced state, the two semicircular partitions 5 are controlled to be in a spliced state to wrap the first half auger 3 and the second half auger 4. At this time, the first driving unit drives the first half auger 3 and the second half auger 4 to rotate, and the raw material moves from the lower part to the upper part of the semicircular partition 5, forming an up and down circulation stirring. When the first half auger 3 and the second half auger 4 are in a separated state, the two semicircular partitions 5 are controlled to be in a staggered separation state. At this time, the second driving unit drives the first half auger 3 and the second half auger 4 to rotate, and the raw material moves laterally inside and outside the semicircular partition 5, forming a horizontal circulation stirring.
[0020] When the device is used to mix the raw materials of PVC pipes, the raw materials are added into the cylinder 1. At the beginning, the first half auger 3 and the second half auger 4 can be driven to be in a spliced state through the intermediate connecting part, and the two semicircular partitions 5 are controlled to be in a spliced state to wrap the first half auger 3 and the second half auger 4. At this time, the first driving part drives the complete auger formed by the first half auger 3 and the second half auger 4 to rotate. Due to the conveying effect of the auger, the raw materials move from the lower part to the upper part of the semicircular partition 5, and then move to the outside of the semicircular partition 5 to form an up and down circulation stirring. After reaching a predetermined time, the first half auger 3 and the second half auger 4 can be driven to be in a separated state through the intermediate connecting part. When the first half auger 3 and the second half auger 4 are in a separated state, the two semicircular partitions 5 are controlled to be in a staggered separation state. At this time, the second driving part drives the first half auger 3 and the second half auger 4 to rotate. Since a complete auger combination is not formed, the raw materials will not be transported up and down. At this time, the raw materials move laterally inside and outside the semicircular partition 5, forming a horizontal circulation stirring inside and outside the cylinder 1.
[0021] From the above, it can be seen that when the raw materials are mixed using this device, the raw materials can be stirred and mixed in an upward and downward circulation and in a horizontal circulation, which improves the uniformity of stirring and fusion compared to stirring in only one direction.
[0022] like Figure 1 As shown, in some embodiments, the first driving part includes a top frame 7, a first motor 8 is provided on the top frame 7, the first motor 8 is transmission-connected to a first gear 9, the first gear 9 is meshed with a second gear 10, the second gear 10 is sleeved with a first rotating shaft 11, the first rotating shaft 11 is rotationally connected to the cover body 2, a first connecting member 12 is provided at the bottom of the first rotating shaft 11, and a first matching groove is provided at the bottom of the first connecting member 12.

[0024] When one end of the connecting rod 14 cooperates with the first matching groove, it is equivalent to establishing a transmission relationship between the first half auger 3 and the second half auger 4 and the first rotating shaft 11. When the first motor 8 is working, the first motor 8 drives the first gear 9 to rotate, the first gear 9 drives the second gear 10 to rotate, and the second gear 10 drives the first rotating shaft 11 to rotate. The first rotating shaft 11 drives the connecting rod 14 to rotate through the first connecting piece 12, and then drives the first half auger 3 and the second half auger 4 at the bottom of the connecting rod 14 to rotate. At this time, the connecting rod 14 slides with the slider in the annular slide groove composed of two semicircular slide grooves 13, thereby realizing the rotation of the complete auger, so as to produce an up and down conveying effect on the raw materials.

At this time, the second motor 16 works to drive the third gear 17 to rotate, and the third gear 17 drives the fourth gear 18 to rotate. The fourth gear 18 drives the second rotating shaft 19 to rotate, and then drives the connecting block 15 to rotate through the second connecting piece 20, thereby realizing the rotation of the first half auger 3 and the second half auger 4. Since a complete auger combination is not formed, the raw materials will not be transported up and down. At this time, the raw materials move horizontally inside and outside the semicircular partition 5, forming horizontal circulation stirring inside and outside the cylinder 1.

The design of the plurality of stirring rods can further improve the uniformity of stirring of the raw materials during the flow process.
